Detailed description of the invention
Below in conjunction with accompanying drawing, the embodiment of the present invention is specifically described:
Front-suspension system provided by the invention as shown in Figure 1, front-suspension system comprises left and right front-suspension, two of left and right front-suspension by stabilizer rod 10 in succession, two of the left and right erection support 1 being bolted with chassis, erection support 1 plays the whole front-suspension system of accepting in total, and provide rotary support installation site for stabilizer rod 10, upper bracket 7 upper surfaces, two of left and right and operator's compartment are affixed, in erection support 1, be pressed with two self-lubricating plain bearings 13, between stabilizer rod 10 and erection support 1, be connected by plain bearing 13, make on the one hand rotation more smooth and easy, reduce the loss suspending between each assembly that has some setbacks and bring because rotating, adopt on the other hand the maintenance of the minimizing revolute that self-lubricating plain bearing 13 can be larger, compound vibration-damper 9 is bolted with upper bracket 7, be pressed into rubber bush in compound vibration-damper upper end, bolt is through described rubber bush mandrel, erection support 1 is bolted with compound vibration-damper 9, turning-over support mechanism comprises flip-arm 5 and turning-over support bar 2, flip-arm 5 lower ends are fixedly connected with stabilizer rod 13, and flip-arm 5 is bolted with upper bracket 7, turning-over support bar 2 one end adopt latch mode to be arranged on mount pad 1, the other end is designed with oblong draw-in groove, on upper bracket, be welded with strut alignment pin 3, strut alignment pin 3 adopts interference mode cover to have nylon jacket 4, realizing draw-in groove contacts with the soft of strut alignment pin 3, the strut alignment pin 3 being welded on when upset on upper bracket is slided in draw-in groove, in the time being turned to the end position of design, strut alignment pin slides into draw-in groove end and realizes stuck spacing, reach the object of protection shock absorber, therefore the draw-in groove that turning-over support bar 2 coordinates with strut alignment pin 3 and turning-over support bar 2 length needs are strict to be calculated, calculate using the stroke-limit of compound vibration-damper 9 inside as input foundation.
In front-suspension system work process, likely there will be the comparatively situation of the limit, such as upset operating mode, now Vibration damping of the driver's cab device limit compression, easily damage, Gu upper limit position block 6 and lower position block 8 more in turning-over support mechanism, upper and lower limiting stopper is arranged on upper bracket 7 by bolt, limiting stopper is by rubber, derby and regular bolt sulfuration form, the operator's compartment limit press down or uphill process in lean with flip-arm 5, concrete lean when operator's compartment upper limit position block 6 and flip-arm 5 when pressing down the limit, in the time that operator's compartment rises to the limit, lower position block 8 leans with flip-arm 5, avoid shock absorber to be subject to crushing.
Stabilizer rod 10 plays safety and realizes driver's cab turnover function and prevent the effect of operator's compartment because excessively turning on one's side in whole mounting assembly, in this embodiment, stabilizer rod axis adopts the hollow stabilizer rod weight that reduced in the middle solid two ends of hollow design, axis adopts friction welding with end axle, between end axle and flip-arm, adopts hot jacket affixed; In turning-over support body function, two of left and right flip-arm 5 plays the effect of balance adjustment operator's compartment left and right height, in the time that operator's compartment occurs that left and right is uneven, (as rolled or upset operating mode) flip-arm 5 can provide an elastic resistance power by stabilizer rod 10 axis, impel operator's compartment to reply balance, the end portion of flip-arm 5 puts rubber bush, play to alleviate and impact, each component movement displacement is compensated, in the mutual collision of system alleviation each several part in service, play certain damping of vibrations.
As shown in Figure 2, in order to make stabilizer rod 10 in the course of the work, between flip-arm and left and right bearing, do not produce abnormal sound and undue wear, between flip-arm 5 and peace seat bearing 1 and between erection support 1 and stabilizer rod end cap 12, cover has nylon wear plate 11 respectively, and consider that front-suspension system is in actual installation technique, in installation process, stabilizer rod does not skid off from erection support, there is end cap 12 in stabilizer rod tip designs, end cap 12, by two stabilizer rod ends that are bolted to, has played simultaneously and has prevented that dust from entering the object of plain bearing 13.
Below by reference to the accompanying drawings the technical scheme of the embodiment of the present invention is carried out to complete description, it should be noted that described embodiment is only the present invention's part embodiment.Based on the embodiment in the present invention; the every other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work; all belong to the scope of protection of the invention; for example the plain bearing in embodiment 13 is replaced by antifriction-bearing box, or cancels stabilizer rod end cap 12 and change in installation process, introduce temporary fixture to avoid lower erection support 1 to skid off from stabilizer rod 10.
